, Application filed January 6, 1902. Serial No. 38,689. (No model.)

To all whom it may concern.-

Be it known that I, BARNARD COLSETH, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lifting-.Trucks, of which the following is a specification.

This invention relatesto means whereby heavy or bulky articles maybe readily raised from thefloor to bewheeled fromplace to place, and has for its objects to provide means for the purpose indicated that will be simple and'strong in construction and durable and efficient in use. It is designed more particularly to raise and carrya pile of starch-boards, such as are commonly used in the manufacture of confections. Itis often desired to move a pile of these boards from one point truck will be pushedup'toa pileof boards, a' lever pressed down, and the whole pileraised sufficiently to be readily wheeled around.

It consists in the novel features and com-l binations fully described and claimed hereinafter and illustrated in the accompanying drawings, in which Figure 1 is an end view of a truck embodying this invention. Fig. 2 is a front elevation showing a pileofboards raised to be moved. Fig. 3 is a plan View. Fig. 4 is a detail of the lifting mechanism. Fig. 5 is anotherview of the same. Fig. 6 is a detail of the pinion. Figs. 7 and 8 are details of the folding handle. 4

A represents a rectangular truck-frame comprising a longitudinal member a and two lateral members 0t' a ,formin g an open square. This frame is mounted on rollers or casters B to allow .its being easily propelled. Uprights O O upon the lateral frame members are braced by braces c o and support the load lifting and carrying mechanism.

The load is engaged and'rais ed by two uprights bars-D D, bent at the lower extremities to form short hooks d d, as shown in Fig. 2, which engage the lower board E through openings or hand-places 6', cut out of the separating-cleats e. (Shown in dotted lines,

Fig. 1.) The bars D D are projected in to engage the load and then raised by the mech anism shown in Figs. 4 and 5. A longitudinal handle F is turned at the ends to form apair of bent levers ff, one at either endof the truck, which are pivoted at f f to the uprights 00. Short links f f connect the ends of these levers with arms from vertijcally-slidable rack 1members,G G, moving'in guideways in the uprights O O. Asshown, the rack-teeth are somewhat narrow and engage with the teeth of a wide pinion H, which of a short rack 11 on a horizontally-slidable Y member I, which is guided by a keeper iand bearing a? on the upright O and carries a ver-. tical bar 73 engaging with a slotted lug or bearing d on the bar'D. A connecting-link J ispivotally attached at one end, j, to'the Vertically-sliding rack member G'and atthe op posite end, j, with the bar D and is of sufficient length so that it projects diagonally upward from its bearing on the memberG when the load is in position, and thereby securely clamps .the load between the bars.-

The operation of the truck is as follows: The handle is raised,,which lowers the sliding racks and allows the bars D to descend, and simultaneously the mutilated gears engage their racks and draw the bars apart. The

truck is then pushed into position to lift a pile of boards andthe handle pressed down. This causes the sliding racks to raise'and revolve the gear, which'forces the horizontal members I inwardly until the mutilated portion of the gear comes into engagement. The

bars D D are now against the pile of boards and the hooks d d in engagement with the bottom one. A further lowering ofthe handle forces the links J J upward and raises the bars D D and the load. Whenthe handle is pressed to its lowest point, itengages-aconvenient snap hook or catch-k on the-frame A, and the load is ready to'be pushedabout, Guards H are secured tothe innerside of the frame to prevent theload from sliding. If the load is of considerable weight, it is desirable to have a longer leverage than given by the handle, as shown, and at the same time not increase the width of the truck.

This is accomplished by a removable or pivoted extension or handle m. (Shown in detail in Figs. 6 and 7.) The handle an is swung out, pressed down, and then folded back into position, as shown.

While I have shown hooks on the liftingbars to engage the load, it is readily seen that these may be dispensed with in many cases and the bars ridged or corrugated to insure engagement therewith.

Other changes will readily suggest themselves as coming within the scope of my invention, which I do not Wish to limit to the exact construction shown; but

What I claim, and desire to secure by Letters Patent, is-- 1. In a truck, the combination of a frame, a lever pivoted to said frame, a pair of bars or clamps adapted to engage the load and means operated by said lever for automatically projecting the bars forward to engage the load and raising said bars after engagement with the load.

2. In a truck the combination of a rectanto said racks, engaging With bearings on vertical lifting-bars, and links connecting said bars with the vertically-slidable members.

3. The combination in a lifting-truck of lifting-bars a vertically-slidable rack member, a pinion operated by said member,a rackbar operated by a mutilated portion of said pinion to project the lifting-bars, and links connecting said lifting-bars and verticallyslidable member substantially as described.
